A wing screw is a type of screw with two flat "wings" on either side of its head, making it easier to tighten or loosen by hand without the need for tools. The wings provide extra grip, allowing for simple manual turning. Wing screws are often used in situations where frequent adjustments or removals are needed, such as in machinery, furniture, or electrical equipment. They are particularly helpful when quick and easy fastening or unfastening is required without using a screwdriver or wrench.
